Contraintes d'utilisation des Technologies de l'Information GĂ©ographique pour la GIZC en Afrique
www.vertigo.uqam.caInternational audienceThree GIS applications for african coastal environmental are presented: an observatory of coastal environmental changes in Mauritania, costal risk assessments in Ivory Coast and a synthetic approach to the Bijagos Archipelago Biosphere Reserve in Guinea Bissau. The main steps and the results illustrate the different stages of GIS implementation (inventory, analysis and management applications). GIS capabilities for monitoring, environmental changes analysis and modelling are highlighted and discussed. But despite these obvious capabilities, it is clear that the GIS long term success will also depend on organizational and human issues.Cette contribution décrit trois SIG mis en œuvre sur la zone côtière africaine à partir d'objectifs de GIZC : observatoires des changements (Mauritanie), des risques côtiers (Côte d'Ivoire) et planification côtière (Guinée-Bissau). Les principales étapes de leur constitution et les résultats auxquels ils ont conduit sont présentés. Si leurs perspectives d'utilisation sont incontestables notamment pour le suivi, l'analyse et la modélisation des changements et des risques côtiers, il apparaît néanmoins que le succès à long terme de leur implantation est conditionné par divers facteurs institutionnels et humains
Geographic Information System for Integrated Coastal Zone Management in Developing countries: cases studies in Mauritania, CĂ´te d'Ivoire, Guinea-Bissau and Morocco.
372Despite leadership of developed country in GIS field and ICZM field, ICZM and GIS together have been compared to a puzzle. This involves questioning on capacity to put together such ICZM and GIS in developing country. We focus on four of such developing countries to highlight difficulties to understand and to manage costal area with the use og GIS. Sustainable management of coastal areas is critical to the long-term health, safety and welfare of many african comunities of these (and other) countries. Despite their importance, coastal zones are being modified or reclaimed, often driven by economic and financial motives. Coastal management offers the opportunity to illustrate the use of GIS and related spatial information technologies not only on coastal issues but in the broader arena of land use planning. The aim of this contribution is to review, synthesize and analyse experiences on coastal management along coasts of Mauritania, CĂ´te d'Ivoire, Guinea-Bissau and Morocco. This allows us to rank these countries from country with a huge lack of geographical information to country with a lead in GIS technology coupled with a good approach of ICZM. The place of developed countries in this rank is also taken into account
